while installing R on Ubuntu 18, I got this error
The following packages have unmet dependencies: r-base : Depends: r-base-core (>= 4.1.2-1.1804.0) but it is not going to be installed Depends: r-recommended (= 4.1.2-1.1804.0) but it is not going to be installed Recommends: r-base-html but it is not going to be installed E: Unable to correct problems, you have held broken packages.
I have deleted R completely and its previous dependencies.
could you please give a favour? thanks
